Abstract:
Die Erfindung stellt ein aus einem biegeschlaffen, nur auf Zug belastbaren Strang (1) hergestelltes Zugaufnahmemittel zur Verfügung, das die Vorzüge einer aus Strangmaterial geformten Kette besitzt, gleichzeitig aber auf einfache Weise kostengünstig herstellbar ist. Zu diesem Zweck ist bei einem erfindungsgemäßen Mittel der Strang (1) zu drei oder mehr Schlaufenabschnitten (S1,...,Se) gelegt. Gleichzeitig folgt ausgehend vom Anfang (A) des Strangs (1) auf jeden in Richtung des Anfangs (A) versetzt angeordneten vorangehenden Schlaufenabschnitt (S1,..., Se-1) ein in Richtung des Endes des Strangs (1) versetzt angeordneter folgender Schlaufenabschnitt (S2,..., Se ), bis der letzte Schlaufenabschnitt (Se) erreicht ist. Des Weiteren weist jeder Schlaufenabschnitt (S1,..., Se) eine Schlaufe (S) auf, die eine Schlaufenöffnung (0) umgrenzt. Schließlich ist aus dem Strang (1) mindestens eine Masche (M1,..., Me) gebildet ist, indem ein folgender Schlaufenabschnitt ( S2,..., Se ) mit seiner Schlaufe (S) durch die Schlaufenöffnung (0) eines zu ihm benachbart angeordneten vorangehenden Schlaufenabschnitts (S1,..., Se-1) geführt ist.
Abstract:
A process for producing a high strength rope comprising the step of i) providing a uniaxially oriented tape (10) comprising ultra-high molecular weight polyethylene, the tape (10) having a tensile strength of at least 0.9 GPa, and ii) simultaneously twisting and fibrillating the tape (10) into a twisted strand of fibrillated tape with a coherent network of filaments and fibrils. A rope obtainable by the process and products comprising the rope are also disclosed.
Abstract:
Trägerelement (1) für die Aufnahme in einem Zug- oder Lastträgergurt (10) als zug- oder lasttragendes Element, welches im Wesentlichen gurtförmig mit zwei Breitenbegrenzungslinien B1 und B2 im Querschnitt (Q) zur Längserstreckungsrichtung und mit zwei Höhenbegrenzungslinien H1 und H2 ebenso im Querschnitt (Q) zur Längserstreckungsrichtung ausgebildet ist, und welches eine Mehrzahl an synthetischen Fasern im Wesentlichen in der Längserstreckungsrichtung verlaufend umfasst, die in ein polymeres Matrixmaterial eingebettet sind, wobei wenigstens eine der Breitenbegrenzungslinien B1 und B2 und/oder wenigstens eine der Höhenbegrenzungslinien H1 und H2 einen nicht-linearen Verlauf aufweist.
Abstract:
There is disclosed a method of forming an eye end termination on a rope having a core comprising a plurality of multi-strand subropes, and a rope having a core comprising a plurality of multi-strand subropes and at least one eye end termination. In one embodiment, a method of forming an eye end termination (16) on a rope (10) having a core (12) is disclosed. The rope comprises a plurality of multi-strand subropes (14) each of a first strength, and the method comprising the steps of: coupling a pair of subropes ( 14) in the rope core ( 12) together using a multi-strand coupling rope ( 18) of a second strength which is greater than said first strength, to thereby form at least part of the eye end termination (16). The step of coupling the pair of subropes (14) together comprises splicing a first portion of a coupling rope (18) to one of the subropes in the pair of subropes, and splicing a second portion of the coupling rope to the other one of the subropes in the pair of subropes.
Abstract:
A mooring line for an oceanographic buoy system includes four sections. The first section is a protected cable that is connectable to the buoy. The second section is an energy absorbing cable. The third section is a weighted cable. The fourth section is a buoyant cable that is connectable to the anchor. The four sections are connected in series by smooth transitional connections. When the mooring line is deployed, it has an inverse catenary lay.
Abstract:
Apparatus for temporarily holding back a tensioned rope from one or more bollard pins (12) on a deck of a vessel. The apparatus comprises: a wedge thimble (32) inserted or insertable into an eye at an upper end of the rope; and a locking element (50) positionable to act between the wedge thimble (32) and the or each bollard pin (12) to transfer tension load from the rope to the or each bollard pin. At least one support part (14) can be coupled to at least one bollard pin (12), the locking element then being cooperable with the or each bollard pin via the support part. The locking element is movable relative to the wedge thimble or is removable from the wedge thimble. For example, the locking element may be a rod that can be inserted into a bore of the wedge thimble.

Abstract:
A synthetic fiber rope having an armor cover layer (3) formed of flexible synthetic resin to cover the outer peripheries of a plurality of strands (2) of synthetic fiber constituting the outer peripheral side of the synthetic fiber rope. And the position of the cab in the elevator shaft is pre-set by one colored region of the armor cover layer (3) lengthwise of the synthetic fiber rope, on the basis of the relationship between the colored region and the sheave having the main rope entrained therearound, so as to provide the synthetic fiber rope with a position index function. This makes the index to be easily identified even after the long-term use of the elevator, excluding defective conditions caused by the index becoming unidentifiable due to wear with time or the like. Therefore, it is possible to properly cope with operations for rescuing passengers from the cab during accidental stoppage and to speed up rescue operations.
